Inspired by Seanswee's “Simplified Preston Iris Ring Holders”, I created these iris ring holders with taller side walls to reduce the chance of any rings accidentally rolling away during those curb-hopping cart moves. The front and back walls are a little higher (the rear is higher so there's an angled cross-section) and the iris ring sits at 50% engagement.
There are versions for 4, 5, 6, 8, 10, and 11 rings. The 10-ring version is 236mm wide and fits on a 256mm print bed (Bambu X1C, P1P, P1S, A1) or 250mm Prusa MK4 print bed. The 11-ring version fits diagonally across a 256mm print bed. The 8-ring version is 190mm wide.
Model photo shown is 8-slot version, printed in black PETG-HF with 0.4mm nozzle, 0.2mm layer height, 13% cubic infill, 3 walls, 3 top/bottom layers, and uses approx 150g of filament; 3 hr print time on X1C.
Edit Dec 28 2024: Added 5- and 11- slot versions.
